A Multi-Service Bit and Power Allocation in WiMAX Networks

摘要：

WiMAX, as a key standard in last-mile access, is expected to support QoS guarantees for multiservices. Developing adaptive bit and power allocation according to quality of service (QoS)requirements is important to different services. In this paper, an adaptive multi-service bit and power allocation based on game theory is proposed for orthogonal frequency division multiplexing (OFDM)WiMAX networks. Considering QoS abilities that each sub-channel could support, the allocation is described as non-cooperation games between subchannels. Meanwhile, the optimal power is derived. The limitation of traditional approach and its discreteness are improved. Simulation results indicate that the multi-service adaptive bit and power allocation makes WiMAX networks support more users of multi-service on the basis of meeting QoS.
